It isn't enough for the government to give lip service or to symbolically say that it derives its authority from the citizens. Sometimes the govt. forgets and has to be forced to remember who its parent is, as in for example the case of Miranda vs. Arizona (from which comes the famous 'Miranda rights' that police must recite during arrests). If we want to follow the example of the royal countries and commonwealths in which protection and rights are derived from the government (which is un-American), then sure no weapons deemed unnecessary by our parent, our government, should be permitted. If we still believe that authority and the duty to protect is derived from citizens, then the govt. has no business stripping citizens of weapons. We are the authority, and we allow the govt. powers and allow it to have a military, not the other way around. If you give up the right to 'Bear arms' you acknowledge authority is derived from the govt. and only what the govt. allows trickles down to us. You may as well just go ahead and hand over power over the country to someone really smart who will do a better job of ruling than we the people, because that is eventually what you will do if you give up the right to bear arms. Then our republic turns into a govt. for the govt. by the govt. and screws we the people. As it is its already gotten us into wars that it shouldn't have and disrespected us. It is testing us once again, pushing to become the parent instead of the child.
